In the year of his death, Adolphe Geshé published the first work of a new series intitled Pensées pour penser. As in his previous series Dieu pour penser, Gesché starts with the problem of evil. He invites the reader himself to reconstruct what he intends to think. It is precisely what the present article means to do, in raising three questions: 1. Can evil be an object of explanation? 2. Has God been surprised by the idea of evil? 3. How are we today to understand the doctrine of original sin?
